4 Channel Spectrum Analyzer, Ham radio Mag., Oct. 1972, page 6. I think this used a single channel scope as a base. or go here for kits you can build for the "Poor Man's Spectrum Analyzer": http://www.science-workshop.com/ (http://www.science-workshop.com/[/color) (http://www.science-workshop.com/systemdiagram_gif.gif) Title: Re: HOMEBREW PANADAPTOR? Post by: WA1GFZ on August 21, 2005, 09:23:40 PM I've used the scope sweep ramp signal to tune a VCO. A CA3089 if strip was used for the log amp as the meter output circuiy has about of 40 dB of dynamic range, I Suggest you save your money and time and invest in a HP141. You will end up much happier.
